"SAN FRANCISCO -- The U.S. Navy plans to test hundreds of homes for radiation in a remote San Francisco neighborhood after an object containing radium was found beneath an unoccupied residence in the area last fall, city officials said on Tuesday.
In the coming weeks Navy officials will begin surveying about 600 homes on Treasure Island, a manmade land mass in the San Francisco Bay that once served as a naval base, said Bob Beck, a director with the city's Treasure Island Development Authority.
A full plan for the survey is still being developed, but officials will likely use handheld scanning devices on the ground floors of homes to detect possible radioactivity underneath them, Beck said."
